now both 6809-6309 cards are working.

many thanks

hello sir
the processor isEF68B09EP, so no oscilator on the chip
JP2 is NOT made, just the jumper is on 1 contact
JP1 is made to RO
the "6809 CPU ASSIST09 i received that together with the gal 48k+16k rom
i even still not see no pulses, on i/o board.
thanks

hello sir
can you look once on that board.
the processor is an HD63C09EC, so normaly no oscillator build in
is SW3 correct, on "C"

hello sir
i tryed some changes on my cpu board, the processor is an EF68B09EP, so no oscillator on he chip
i removed the JP2, just connected on 1 side.
the JP1 is just connected to 1 pin
sw2 is A15 and A14 is off-------- A13,1A12,A11,A10,A9,A8 is ON
